I have a ST4120 . When I bought it there was no pen with it , so I used a wireless mouse. I bought a MFI CD Set of 6 discs and a floppy from Fujitsu. To start from a fresh install with a new pen so I can get the tablet part working. Is there a way to check the hardware part of the tablet to make sure its ok? I hope I explained that ok. Thanks funnnyfarm
